Recently, the major coins have been really frustrating, with prices swinging wildly up and down, and liquidity has basically been wiped out. In this kind of market, it might be better to change your approach—look for those smaller tokens that are running their own independent trends, at least they won't get chopped back and forth like the majors. If you still want to trade the major coins, it's best not to use too much leverage, 10x should be enough. The most frustrating thing is when you judge the direction correctly, but get shaken out halfway, and by the time the real rally comes, you're already off the train.
